I was referring to the fish in question, not the Zaire green in your photo.
I'd based my initial opinion on the dorsal view of the fish in post # 9 as well as the side view of the last fish in same post. I did not see the close-up photo of the head.
That fish is certainly not a Zaire Green.
I've yet to see a wild Ornate, Buettikofferi, Weeksii or Zaire green with a hunched back. Judging by the dorsal view of the fish in the photo(head shape and pectorial fin pattern) i would have insisted on Lapradei(young fish) or Lapradei. However, the side view suggests otherwise.
It's somewhat confusing and the blurry photos don't help matters. Is this a farm raised fish ??? May be a hybrid.
